<h3>
Answer: Choice B</h3>
Reason:
Choices A, C and D have repeated x values. It allows us to rule them out.
Table A has x = 6 repeating. Table C has x = 3 and x = -3 repeated. Table D has x = 4 and x = 5 show up twice each.
Whenever we have repeated x values, it indicates we do <u>not</u> have a function. A function is only possible when each x value goes to exactly one y value only.
Table A has the input x = 6 lead to y = 2 and y = -2 at the same time. Table C and table D are a similar story. So this is another way to rule out choices A, C and D.
Luckily table B has no repeated x values. Each x input leads to exactly one and only one y output. Therefore, <u>table B</u> is a function.
Side Note: the y values can repeat, but the function won't be one-to-one.
Answer: -2.25
Step-by-step explanation:
-2 4/9 or -2.25
Convert this to decimal
-2 4/9
4/9=0.4444
Add to the 2
-2.4444
-2.444 or -2.25
In negative rule,the lower the value,the greater the number
Therefore,
-2.25 is greater than -2.444
Answer:
The value of
is 
Step-by-step explanation:
Rearrange the terms so that all terms containing the variable are on one side of the equation and all constant terms are on the other side.
Subtract
from both the sides.

Answer:
O = (3,3)
Explanation:
The <em>altitude</em> of a triangle is the perpendicular from a vertex to the opposite side.
The orthocentre (O) of a triangle is the point where the three vertices intersect.
We must find the equations for only two of the altitudes, because the third will also intersect at that point.
===============
Your three points make a right triangle.
The altitude of B is side AC.
The altitude of C is sde AB.
Their point of intersection at A (3,3) is the orthocentre of thetriangle.
Just put it depends if they’re in a rush anything is possible
